1.	Take the spherical hollow ball and cut a spherical part AOB along the circumference perpendicular to XY axis as shown (A). Observe the AOB part. One of its parts is depressed inwards where as the opposite parts is bilged outward. Both the inwards and outwards parts are curved. What are these parts calles ?Any outwardly bulging curved surface is Convex and inwardly depressed curved surface is Concave. If the same process is performed for a transformed spherical hollow glass then get a transparent curved part of the glass which has two opposite planes, one convex and another concave.A spherical mirror in which the outwardly curved part works as a reflector is called Convex mirror.The bulged inward part i.e., the centre of the of spherical mirror works as reflector is called Concave mirror. 1. What are these spherical parts known as?2. What is a convex mirror?3. What is concave mirror?
